Okwu mmalite

Succinic acid bụ ngwakọta organic. Ihe na-esonụ bụ mmalite nke njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke succinic acid:

Ogo:

- Ọdịdị: kristal siri ike na-enweghị agba

- Solubility: Succinic acid na-adị mfe soluble na mmiri na ụfọdụ ihe mgbaze organic

- Njirimara kemịkalụ: Succinic acid bụ acid na-adịghị ike nke na-emeghachi omume na alkali iji mepụta nnu. Ngwongwo kemịkalụ ndị ọzọ gụnyere mmeghachi omume na mmanya, ketones, esters, wdg, nke nwere ike ime ka akpịrị ịkpọ nkụ, esterification, carboxylic acidification na mmeghachi omume ndị ọzọ.

Jiri:

- Eji ụlọ ọrụ eme ihe: Enwere ike iji Succinic acid mee ihe na nkwadebe nke polymers dị ka plastik, resins na roba, dị ka plasticizers, modifiers, coatings na adhesives.

Usoro:

Enwere ọtụtụ ụzọ nkwadebe kpọmkwem, gụnyere ime butalicic acid na hydrogen n'ihu ihe na-eme ka ọ bụrụ ihe na-akpata, ma ọ bụ ime ya na carbamate.

Ozi nchekwa:

- Zere kọntaktị na akpụkpọ ahụ na anya, ma were ọtụtụ mmiri sachaa ozugbo ma ọ bụrụ na a kpọtụrụ ya.

- Zere iku ume succinic acid uzuzu ma ọ bụ vapors ma nọgide na-arụ ọrụ ikuku nke ọma.

-Ekwesịrị iyi akụrụngwa nchebe kwesịrị ekwesị dị ka uwe, enyo na uwe nchebe mgbe ị na-eji succinic acid.
